2. Phase Rotation Meter Non-contact 3 Phase Rotation Meter AC 70~600V Phase Sequence Rotation Tester High Magnetic Induction Rotation Meter Auto Power Off Phase Meter with LED, 20-inch Clamp Lead,Handbag

Features :

  • 【Professional & Multifunctional Non-contact 3 Phase Rotation Meter】Our non-contact phase rotation meter has multiple functions of phase sequence detection, open phase detection, circuit break detection, live power detection and voltage detection. Phase rotation meter can quickly and accurately detect the open phase position of the line. 3 phase rotation meter is a good helper for line maintenance and distribution boxes detection. Note: XZ-02 cannot perform 3-phase motor rotation detection.
  • 【Non-contact Inductive Detection】Different from the traditional phase sequence detection,which must pull 3 phase wire and connect to exposed live wire.Our phase rotation meter adopts a clamp-type non-contact inductive measurement,without removing phase wire or touching exposed high-volt live wire.Phase sequence can be detected by simply clamping insulating sheath of 3 phase live wire with three clamps,which greatly improves safety of the test,effectively protects the personal safety of operator.
  • 【Ultra-high Magnetic Induction Phase Rotation Meter】The three super-inductive and high-insulation clamps of the non-contact phase rotation tester are made of ultra-high magnetic induction alloy material. The ultra-high magnetic induction alloy has high magnetic permeability of weak magnetic field, which greatly improves the sensitivity and reliability of detection.
  • 【Phase Sequence/Open Phase Detection Phase Rotation Meter】When the A, B, C phase indicators are all on, the R indicator will be on when the phase is positive, and the L indicator will be on when the phase is negative. When one or more of the A, B, C phase indicators are not on, it means that the corresponding phase line of the phase indicator is lack of power. Please check the lack of power of the corresponding phase, and the positive and negative phase indications are meaningless at this time.
  • 【Live Power Detection&Circuit Break Detection】Phase rotation meter can detect whether the wire is live or not, and can also judge if there is a fault in the line, quickly find the location of the circuit break. Clamp any one of the clamps to the wire under test, if the wire has electricity (AC 70~600V within the voltage setting range of the live wire), the corresponding A,B,C phase indicators will be on; if the wire lacks electricity, the corresponding A,B,C phase indicators will not light up.
  • 【Auto Power Off & LED Indicators & Portable Carrying Bag Phase Rotation Meter】After about 5 minutes of power on, if the phase rotation tester is in a state of no operation, the 3 phase rotation meter will automatically shut down to help you save power and prolong the service life of the battery. High-definition indicators of the phase rotation meter could help you identify problems at a glance. 3 phase rotation tester comes with a carrying bag for easy carrying and storage.
